The 2018 free-agent list is unlike any we've seen in recent memory. With superstars like Manny Machado and Bryce Harper on the open market, the balance in MLB power could drastically shift in any directions.

But it doesn't end with Machado and Harper: Patrick Corbin, Dallas Keuchel and others headline this season's greetings of stars on the market.

Sporting News will keep track of all the latest signings this offseason below.

MLB hot stove tracker, completed deals

Astros add to rotation with Wade Miley

Deal: One year, $4.5 million, plus incentives

Analysis (Gatto): Miley will slot into the middle of Houston's rotation in 2019 after righting himself with the Brewers last season. The 32-year-old left-hander produced a 2.57 ERA in 80 2/3 innings for the NL Central champs, keyed by improved control. He averaged 3.0 walks per nine innings after issuing 5.3 per nine with the Orioles in 2017. His strikeout rate fell to a career-low 5.6 per nine, however.

Greg Holland joins Diamondbacks' late-inning mix

Deal: One year, $3.25 million, plus incentives

Analysis (Gatto): Arizona may have found a super-cheap ninth-inning option here. Holland regained his effectiveness late last season with the Nationals after an awful stretch with the Cardinals, with whom he signed on March 31. The former Royals and Rockies closer allowed just two earned runs in 21 1/3 innings for Washington, although he did issue 10 walks. Arizona could go with Archie Bradley to close, but he's seen as more of a "relief ace" who can pitch multiple innings and in multiple situations.

Analysis (Gatto): The 27-year-old left-hander cratered in 2018 after two decent seasons with the Rangers. He lost his starting spot and finished with a 6.22 ERA. With the Twins, he figures to slot in as the No. 4 or No. 5 starter and serve as a stopgap until the organization's pitching prospects show they're ready.

Blue Jays get deeper in infield with Freddy Galvis

Deal: One year, $4 million, $5 million option for 2020 ($1 million buyout)

Analysis (Gatto): Galvis can potentially fill multiple roles in Toronto: a replacement for incumbent shortstop Lourdes Gurriel Jr. and a bridge to prospect Bo Bichette; a platoon partner for second baseman Devon Travis; or a super utility player who can play three infield spots (second, short and third) and the outfield. Galvis, 29, played in all 162 games for the Padres last season and tied a career high with 67 RBIs.

Neil Walker to add experience to Marlins

Deal: One year, $2 million

Analysis (Gatto): Walker, 33, is embracing the idea of being a mentor to Miami's young players, drawing on the lessons he learned as an up-and-coming player with Pirates several years back. The switch-hitting veteran is a fit as a platoon player at first or third base, and he could also spell Starlin Castro at second base. Walker is coming off a bad season with the Yankees; he produced just a 79 OPS+, a career low for a full season.

Analysis (Gatto): Texas has added multiple free-agent pitchers this offseason, and Kelley is part of the group. The 34-year-old right-hander shined with the A's (2.16 ERA in 16 2/3 innings) last year after being DFA'd by the Nationals over an on-field fit of pique. He figures to begin the season as a part of Texas' bridge to closer Jose Leclerc.

Mets find lefty relief with Justin Wilson

Deal: Two years, $10 million

Analysis (Gatto): Wilson fills a big need for New York, which previously counted nonroster invitee Luis Avilan and youngster Daniel Zamora as its primary lefty relievers. He struck out 69 batters in just 54 2/3 innings for the Cubs in 2018, but his 33 walks were cause for concern. Durability is one of Wilson's strong suits; he has pitched in 58 or more games in each of his six full major league seasons.

Dodgers snag A.J. Pollock

Deal: Four years, $50 million, $15 million vesting option for 2023, opt-out after three seasons ($5 million buyout)

Analysis (Gatto): LA replenishes its outfield stock with Pollock after trading Yasiel Puig and Matt Kemp to the Reds. He's one of the National League's top all-around center fielders when healthy, but there are doubts after he played in just 112 and 113 games, respectively, in 2017 and 2018. He hit a career-high 21 home runs last year but his .800 OPS was barely above average.

Retooling Mariners bring in Hunter Strickland

Deal: One year, $1.3 million, plus incentives

Analysis (Gatto): Strickland is part of Seattle's buy-and-sell offseason. He'll have an opportunity to recover from a downturn in performance last season with the Giants. The 30-year-old right-hander registered a career-low 7.3 strikeouts (against 4.2 walks per nine) in 2018, which contributed to a career-high 4.42 FIP. He registered 14 saves as a fill-in closer, but did it while posting a career-high 3.97 ERA.

Indians re-sign Oliver Perez

Deal: One year, $2.5 million, $2.75 million vesting option for 2020

Analysis (Gatto): Perez, 37, was rewarded for becoming a lights-out lefty specialist with Cleveland last season. He allowed just 24 baserunners in 32 1/3 innings over 51 appearances. The Tribe's 'pen remains deep even after losing Cody Allen as a free agent in the offseason.

Marco Estrada joins A's

Deal: One year, $4 million

Analysis (Gatto): Oakland now has two certain starters with Estrada and fellow offseason signee Mike Fiers. Estrada, 35, is coming off a career-worst season with the Blue Jays (5.64 ERA/5.44 FIP, 29 home runs allowed) and will be three years removed from an All-Star appearance when the 2019 season begins.

Rangers complete infield with Asdrubal Cabrera

Deal: One year, $3.5 million

Analysis (Gatto): Cabrera begins his Texas tenure as the successor to retired third baseman Adrian Beltre, but he could also fill a utility role if needed. He still has the hands of a high-level shortstop, but age (he'll be 33 on Opening Day) and injuries have taken away some of his range. His switch-hit power should play well at Globe Life Park. He's coming off a 23-home-run season with the Mets and Phillies.

Yankees deepen 'pen with Adam Ottavino

Deal: Three years, $27 million

Analysis (Gatto): New York is now five-deep in high-quality relievers after adding Ottavino to the foursome of Aroldis Chapman, Dellin Betances, Zach Britton and Chad Green. Ottavino, 33, used a wipeout slider and mid-90s fastball to rack up 112 strikeouts in 77 2/3 innings with the Rockies last season. That profile fits perfectly with New York's K-heavy bullpen.

Giants add rotation insurance with Drew Pomeranz

Deal: One year, $1.5 million, plus incentives

Analysis (Gatto): Pomeranz went through a lost season with the Red Sox in 2018. He pitched just 74 innings after averaging 172-plus the previous two years and posted a 6.08 ERA.San Francisco was seeking rotation depth to help protect Dereck Rodriguez and Andrew Suarez, who became key contributors as rookies last year. Pomeranz could be more than just depth if he rediscovers his 2016-17 form (132 ERA+, 9.4 K/9).

Braves bring back Nick Markakis

Deal: One year, $4 million, club option for 2020 ($2 million buyout)

Analysis (Gatto): Much was made about Markakis' quiet leadership, professionalism and durability as the Braves were winning the NL East last year. Much was also made about his second-half swoon at the plate (.258/.332/.369 slash line, four home runs after the All-Star break). After a lot of chatter about A.J. Pollock and even Bryce Harper, Atlanta seems content with beginning the 2019 season with the same outfield alignment as the one that ended the 2018 campaign: Ronald Acuna Jr. in left, Ender Inciarte in center and Markakis in right.

Diamondbacks bring in Wilmer Flores

Deal: One year, $3.75 million, $6.25 million club option for 2020 ($500,000 buyout)

Analysis (Gatto): Flores has a legitimate chance to earn everyday at-bats after being mostly a platoon player with the Mets. The D-backs plan on making him their regular second baseman and shifting Ketel Marte to center field to replace A.J. Pollock. They'll sacrifice some defense (Flores is not the smoothest fielder) as they hope he becomes a threat at Chase Field. He has a career 3.4 percent home run rate, but it was 4.8 and 5.0 percent, respectively, in 2016 and 2017. The right-handed hitting Flores also had extreme reverse splits in 2018 (10 of his 11 homers were hit vs. right-handers), a reversal of his career norms.

Angels close the deal with Cody Allen

Deal: One year, $8.5 million, plus incentives

Analysis (Gatto): Allen, 30, faltered last season with the Indians. He allowed a career-high 11 home runs and issued 4.4 walks per nine innings, leading to a career-worst 4.70 ERA. LA is counting on a rebound in what will be another contract year for him. If he has a big 2019, he could land one more long-term contract.

Rays sign Avisail Garcia

Deal: One year, $3.5 million, plus incentives

Analysis (Gatto): Tampa Bay is getting a 27-year-old outfielder/DHwhose robust production in 2017 (137 OPS+) appears to be an outlier. His 2018 numbers (96 OPS+ 92 wRC+) tracked much closer to the rest of his career, although he did show increased power (career-high 19 homers, .202 ISO). Garcia figures to take at-bats from right fielder Austin Meadows and DH Ji-Man Choi as a semi-regular.

Analysis (Janower): The Yankees' agreement with LeMahieu seems to indicate that they won't sign Manny Machado. LeMahieu's contract was first reported by Jack Curry of YES Network. The 2016 NL batting champ, who set a career high with 15 home runs last season, certainly benefitted from playing most of his career in the hitter-friendly Coors Field. LeMahieu still is a stronger fielder, as his three Gold Gloves show, but the signing creates a logjam in the infield with Miguel Andujar, Gleyber Torres, Troy Tulowitzki, and Luke Voit. Add in Didi Gregorious when he returns from injury and it's tough to envision the Yankees adding Machado to the picture.

Analysis (Gatto): Another FOB (Friend of Brodie) is headed to Flushing. Lowrie joins Robinson Cano as former clients of agent-turned-GM Brodie Van Wagenen who are moving to New York in 2019. Lowrie is more than a guy getting a new gig from a buddy, though; the 34-year-old infielder is coming off a career season with the A's (23 home runs, 99 RBIs, .801 OPS, 4.8 bWAR). The switch-hitting Lowrie will add versatility to the Mets' infield; he has played mostly second base the past four seasons but was an everyday shortstop before then. Previous super sub Jeff McNeil is expected to see more time in the outfield with Lowrie's arrival.

Analysis (Janower): It's not Bryce Harper, but the Nationals continued their busy offseason by filling a hole in the middle of their infield. They reportedly agreed to a contract with veteran second baseman Dozier (per Jeff Passan of ESPN), who could be a strong bounce-back candidate. Dozier has a good shot to be Washington's starting second baseman, taking the role from Daniel Murphy, who was traded in August. After receiving MVP votes in three straight seasons, Dozier struggled in 2018 in 151 games between the Twins and Dodgers, posting an OPS of just .696. If he can resemble his form from 2015-17, this could turn into a steal for the Nationals.

Analysis (Gatto): Grandal was thought to be in line for a multiyear pact even after a dreadful postseason with the Dodgers. His switch-hit power (at least 22 home runs in each of the past three seasons) and overall defensive work made him one of the top options in a thin free-agent catcher market. There were unsubstantiated reports Grandal turned down a four-year, $64 million offer from the Mets. Now, with spring training about a month away, Grandal is about to sign a contract (per Ken Rosenthal of The Athletic and Tim Brown of Yahoo Sports) that is worth a little more than the qualifying offer he turned down from LA and will send him back into the market next winter.

Analysis (Rivera): The White Sox bring Herrera back to the AL Central after spending a (very poor) half season on the East coast with the Nationals. Herrera's familiarity with AL Central opponents could help him rebound, and he should pair nicely with Alex Colomé at the back end of the Chicago 'pen.

Zach Britton returning to Yankees' bullpen, reports say

Deal: Three years, $39 million, $14 million club option for 2022/player opt-out after 2020 season.

Analysis (Gatto): New York management digs into the vault to re-sign Britton, who didn't pitch like the dominant reliever the Bombers expected him to be after they acquired him from the Orioles last July. Yanks brass is counting on Britton, 31, regaining command of his power sinker and serving as a big link in the late-inning bridge to closer Aroldis Chapman.

David Robertson to be Phillies' relief 'ace'

Deal: Two years, $23 million, $12 million team option for 2021.

Analysis (Gatto): Robertson, 33, has closing experience, but he won't be limited to the ninth inning with his new club. Navigating high-leverage situations will be his primary focus. "If I've got to pitch in the sixth, seventh or eighth or even the ninth, it doesn't matter. I just want to be in the back end of the bullpen when the big outs need to be made," he told reporters (per MLB.com) at his introductory press conference.

Mariners land Yusei Kikuchi

Deal: Three years, $43 million, $13 million player option for 2022, four-year, $66 million club option (2022-25).

Analysis (Gatto): Seattle's buy-and-sell offseason continues with a big international purchase. Kikuchi, 27, is coming from Japan to claim a spot in the middle of the M's rotation. He won't be a workhorse from the start, however; Seattle plans on limiting his innings, mostly through extra rest and short starts, as he makes the transition to the majors and as the retooling M's plan for 2020 and beyond.

Nelson Cruz signs one-year deal with Twins

Deal: One year, $14 million. $12 million team option for 2020.

Analysis (Rivera): Signing Cruz to a one-year deal is a good move for the Twins, who get a veteran bopper in the middle of the lineup. Minnesota likely won't compete for anything more than a second wild-card spot at their absolute best, so this makes sense as a buy-and-trade move for them, as well. Should Cruz perform, I wouldn't be surprised if the 38-year-old is flipped at the trade deadline to a team that's in the hunt for a playoff spot.

Joakim Soria joining A's bullpen

Deal: Two years, $15 million

Analysis (Gatto): Oakland makes a move to keep its relief corps strong. Soria, 34, was the White Sox's closer for a time last season before being traded to the Brewers, for whom he pitched in middle relief. He appeared in 66 games total in 2018, with a 3.12 ERA (2.43 FIP) and 11.1 strikeouts per nine innings. Soria will join a setup group that includes Fernando Rodney, Lou Trivino, Ryan Buchter and Yusmeiro Petit.

Analysis (Gatto): As Derrick Goold of the St. Louis Post-Dispatch notes, the Redbirds were interested in Miller before he signed with the Yankees in the 2014-15 offseason. They're about to capitalize on their second chance. Miller was one of baseball's best relievers before injuries marred his 2018 season with the Indians. He posted a 1.72 ERA and averaged 14.5 strikeouts per nine innings from 2014-17. He can set up or close, but St. Louis has an opening in the ninth inning with Bud Norris becoming a free agent. Regardless of his role, Miller will give the Cards much-needed bullpen help from the left side.

Analysis (Gatto): Sanchez, somehow, earned himself another decent contract (figures reported by Anthony Fenech of the Detroit Free Press) after his five-year, $80 million deal with the Tigers turned into an albatross. The right-hander was a rotation stalwart for the division-champion Braves last year after joining the team in mid-March. He posted a 2.83 ERA (3.62 FIP) in 25 games (24 starts). Now he'll try to beat Atlanta as Washington's new No. 4 starter, replacing the traded Tanner Roark.

Analysis (Gatto): Cahill was one of the unexpected keys to the A's success last season, and now comes his reward. He and fellow free agent Matt Harvey will fill out a rotation that looks, on paper anyway, to be unimposing. One potential red flag about the 30-year-old Cahill: His home-and-road splits were stark last season. He fashioned a 1.84 ERA and 0.91 WHIP at the Oakland Coliseum as opposed to a 6.41 ERA and 1.58 WHIP on the road.

Analysis (Gatto): The 33-year-old Murphy fills a need on the Rockies' infield, but not the one you might assume. Rather than slide in for departed second baseman DJ LeMahieu, Murphy is expected to play first base, per Ken Rosenthal of The Athletic. That would ensure a change of position/role for Ian Desmond. Murphy was never fully healthy last season; he played with soreness in his surgically repaired right knee. His offense returned to the levels he produced while with the Mets (.454 slugging percentage, 106 OPS+), but home games at Coors Field should help improve those numbers.

Analysis (Rivera): Can the Dark Knight rise? That's the question everyone is asking. This was supposed to be the winter of Harvey, after all, but given the way Harvey's career has unfolded - injuries, ineffectiveness - it's hard to see how he can reimagine himself once again. There's no such thing as a bad one-year deal, after all.

Jeurys Familia returns to Mets on three-year deal

Deal: Three years, $30 million.

Analysis (Rivera): Familia was a pretty good Met, 2015 World Series aside, who wanted to be in Queens once again. This is a good move by new Mets GM Brodie Van Wagenen, who continues to re-shape the roster in his image. Spending money to shore up the bridge to new closer Edwin Diaz is a big deal, as the Mets have made bargain-bin signings in the bullpen in recent years. Familia is a good option to set up Diaz, but there's more work to be done.

Yankees bring back J.A. Happ

Deal: Two years, $34 million with a vesting option for a third year.

Analysis (Rivera): The Yankees needed to solidify the rotation, and it's exactly what you're getting with the 36-year-old lefty. Happ isn't going to overwhelm a lot of hitters, but he's a consistent back-end-of-the-rotation guy who the Yankees desperately needed. Re-signing Happ shouldn't preclude them from continuing to fix their rotation, but it's a good insurance move for their 2019 season.

Mets get backstop help, sign Wilson Ramos

Deal: Two years, $19.5 million.

Analysis (Rivera): This is a really good move for the Mets. Ramos is one of the more underrated catchers in baseball, especially offensively. In 111 games between Tampa Bay and Philadelphia last year, Ramos hit .306 with a 130 OPS+. Health is key, as per usual, but Ramos is a good signing for a fair price.

Rays add starting pitcher Charlie Morton

Deal: Two years, $30 million.

Analysis (Jacob Janower): Morton has rejuvenated his career over the last two seasons, posting a 3.36 (3.53 FIP), 1.176 WHIP, and a 10.4 K/9 in 55 starts with the Astros. At the age of 35, he will provide a veteran presence to a young Rays pitching staff that proved it can contend in 2018 and includes reigning AL Cy Young winner Blake Snell.

The Rays frequently used an "opener" last season, but with Morton's ability to eat innings (313 2/3 in 2017 and 2018) it's reasonable to assume he will be used in a more traditional starting role.

Patrick Corbin signs mega-deal with Nationals

Deal: Six years, $140 million.

Analysis (Rivera): Wow. Patrick Corbin had a great year with the Diamondbacks. He pitched to a 3.15 ERA (2.47 FIP), 1.050 WHIP, 246 strikeouts in 200 innings. He even finished fifth in the Cy Young voting. That's a great year, in fact, it was his best year, in his Age 29 season.

But before 2018, Corbin pitched over 200 innings just once (2013, 208 1/3 innings) and all of his numbers are good but not great: a 4.12 ERA (3.96 FIP), 1.348 WHIP, 104 ERA+.

So really, does anyone really know what Patrick Corbin is? Corbin is solid, even good, in a good year. But so far in his career, he's traded good and bad years routinely.

Is he worth $23 million a year through his age 35 season? It's tough to say. It's a bold move for the Nats, who have banked on pitching in the past, and has worked at times. Hopefully their faith will be rewarded this time and Corbin continues to trend up and prove that 2018 wasn't an aberration.

Analysis (Rivera): McCann had his best years with the Braves, and the local boy returns home on a short deal. After a lackluster stint with the Yankees, McCann didn't refind much of his offense with the Astros, but his leadership was felt en route to raising the Commissioner's Trophy following the 2017 World Series. The Braves are likely hoping for more of the same with a young team.

Analysis (Rivera): There's no such thing as a bad one-year deal, and even though the $23 million price tag seems hefty, getting a former MVP candidate in a year where the Braves are going to challenge for a World Series isn't a bad thing.

While an injury riddled season sapped Donaldson of prime production with the Blue Jays, in 16 games with the Indians he reverted to his old self: three home runs, .280 average and a 146 OPS+ for the Tribe. It's a good signing for the Braves, with potential to be great.

Nationals sign catcher Kurt Suzuki

Deal: Two years, $10 million.

Analysis (Rivera): Kurt Suzuki has aged like a fine wine, hitting to a 128 OPS+ in 2017 and a 108 OPS+ in 2018. Previously with Washington (2012-13), he hit .237 with eight home runs in 122 games. Suzuki has only gotten better with age and helps fortify defense behind the dish for the Nats.

Analysis (Rivera): Gardner was slated to make $11 million in 2019, but the Yankees bought out his deal ($2 million) and paid him a new, $7.5 million contract, essentially saving a few million bucks.

Gardner is an aging outfielder who had his worst season in pinstripes, but much like Sabathia, the Yankees value his veteran presence and leadership in the clubhouse. He's also very good at working counts, which adds something to a lineup.

Analysis (Rivera): Freese provided a proven, veteran bat throughout the playoffs for the Dodgers. Declining his deal and bringing him back was the smart thing to do, and they save about $4 1/2 million in doing so.

Analysis (Rivera): Admittedly, this signing was a bit confusing, but when you dig into the numbers a bit deeper, it makes some sense. Sabathia had good fifth-starter numbers in 2018, and his leadership means a lot to the club.

While the signing came as a surprise to some, the numbers are there, and Sabathia and the Yankees feel like they have unfinished business.

Analysis (Rivera): Rosenthal last pitched in 2017, throwing to a 3.40 ERA in 50 games (2.17 FIP). He underwent Tommy John surgery in 2017, spending 2018 rehabbing the injury. It's a low-risk move for the Nats, who give Sean Doolittle a little bit of help in the back end of the bullpen should Rosenthal rebound.

Analysis (Tom Gatto): The 2018 World Series MVP, who will turn 36 on April 13, could become the right-handed half of a first-base platoon with Mitch Moreland, but he's versatile enough to also make spot starts at the corner outfield positions, second base and third base. One thing seems certain: Pearce will face a lot of left-handed pitching; he owns an .852 OPS in 908 lifetime plate appearances vs. southpaws.
